Figure 5. Enzyme assay of PhaJ1 with the substrates of 3-hydroxybutyryl-CoA (3HB-CoA) and crotonyl-CoA.

Figure 5

HPLC analysis of the products of dehydration and hydration of 3HB-CoA (A) and crotonyl-CoA (B), respectively, as catalyzed by PhaJ1. (C) Evaluation of the stereospecificity of PhaJ1. The hydration of crotonyl-CoA as catalyzed by PhaJ1 coupled with crude PHA synthase located on nPHA granules that were isolated from H. mediterranei EPSΔphaJ1 was spectrophotometrically monitored at 412 nm.
